JOHN G. KERST, OF SPRINGFIELD, ILLINOIS.

SHOCKING ACCESSORY FOR HARVESTING-MACHINES.

Application filed July 10, 1913.

To all @071 am it may concern:

Be it known that 1, JOHN G. KnRsT, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Shocking Accessories for HarvestingMachines, of which the following is a specification.

My invention relates to improvements in grain harvesting machines, and refers more particularly to accessories to the ordinary types of grain harvesters.

The main object of my invention is to provide an accessory to a harvester which will receive the bundles of grain as they are delivered from the harvester, and upon which the grain shock may be assembled, and later delivered to the ground in its completed form. V

A further object is to provide means for righting the bundles and delivering them butt end down with greatest facility to the assembling floor of my accessory, and to provide an easily controlled and efficient device for placing the completed shock upon the ground when assembled.

lVith these and other objects in view, the device of my invention consists ofcertain new and useful peculiarities in construction and arrangement of parts which will be hereinafter fully described and pointed out in the appended claims.

In the accompanying drawings wherein is illustrated the preferred embodiment of my invention, like reference numerals refer to like parts throughout the several views.

In the drawings: Figure 1 is a plan view of the device of my invention shown in its working position attached to the main axle of a harvester. Fig. 2 is a side elevation of my device. Fig. 3 is a front elevation of my device. Fig. 4 is a diagram of the driving gears by which the shock-delivering yoke is actuated.

Referring now to the drawings, numeral 1 designates one of the wheels of a harvesting machine, to which the axle 2 of my accessory may be attached by any suitable method, 3 being a traction wheel similar in diameter to the wheel of the harvester and carrying the outer end of axle 2.

Numeral 4 designates a platform or frame carried on the forward end by axle 2 and being supported at the rear by caster wheels 5.

Specification of Letters Patent.

Patented Mar. 23, 1915.

Serial No. 778,413.

Numerals 43 and 44 designate posts supporting side bars 42, and to which any desired side boards may be attached.

It will be noted by reference to Fig. 2 that the platform 4 is lower at the rear end, for a purpose which will be hereinafter fully explained.

Above platform 4, a second platform des ignated as 8 is provided, which platform is supported by upright members 9 from the main frame. On platform 8 are bearing pedestals 13 and 14 in which are mounted parallel shafts 10 and 12. Shaft 12 extends through pedestal 13 on the outer side and is provided with a sprocket wheel 26 adapted to be driven by a chain 7 from a sprocket wheel 6 carried on the hub of the harvester wheel. Shaft '10 is provided with a gear wheel 15 and shaft 12 with a gear 16, which gears are adapted to mesh, gear 16 driving gear 15 in the opposite direction from the revolution of shaft 12. Adjacent pedestal 14, shafts 10 and 12 are provided with another set of gears which are adapted to slide on said shafts, and which are designated respectively, as 17 and 18. Gears 17 and 18 are provided with elongated slide-hubs 22 and 23 which are provided with slide collars and pivoting rings to which are pivoted an actuating lever 25. Lever 25 is pivoted to I a pedestal carried by platform 8 midway between the sliding gears at a point designated as 24. It will be seen that by shifting the actuating lever 25 about the pivoting point 24 the gears 17 and 18 may be thrown into or drawn out of mesh with the gear wheel 29. On the opposite side of pedestal 14 and between said pedestal and a box bearing 20, a gear designated as 21 is mounted on shaft 19. Gear 21 extends downward through a cut-out portion in platform 8 and is adapted to mesh with a gear rack 28 carried on the upper side of shock-delivering bar 27. Brackets 34 extend downward from the under side of the platform 8 and are. provided with pulleys such as 35 for the purpose of guiding the shock-delivering bar.

The shock-delivering device consists of a shock-delivering bar 27 located to travel on a line central with a grain shock, which bar is provided on its rear end with an arcuate arm or yoke 30. The rear end of bar 27 and yoke 36 are supported by a traction wheel 33 whichis adapted to travel on the smooth surface of platform 4.

It will be seen that the method of driving my device is as follows: The harvester wheel travels in a counter-clockwise direction as viewed in Fig. 2 and gear 6 carried thereby will also travel in a counter-clockwise direction, transmitting through chain 7 he same rotation to gear 26 and through the medium of shaft 12 to gears 16 and 18. Gear 15, which is actuated by gear 16, will be rotated in a clockwise direction and also shaft 10 and gear 17. When gear 1'? is drawn into mesh with 29, gear 29 will travel in a counter-clockwise direction and this rotation will be transmitted through shaft 19 to gear 21. Gear 21 being in mesh with gear rack 28, the rack will be actuated backward and yoke 30 will be moved to the position shown in dotted lines in Fig. 1. When gear 18 is in mesh with gear 29, the opposite motion will be transmitted to gear 21 and the gear rack and shock-delivering device will be drawn forward to the position shown in full lines in Fig. 1.

In order to limit the travel of the shockdelivering device I prefer to provide such an arrangement as is shown in Fig. 4. Numeral 48 designates a blank portion in gear 29, the teeth being removed. It will be seen that whenever the gear which is in mesh with gear 29 reaches this blank portion that further revolution in that direc tion will be stopped and that it will be necessary to throw the other gear into mesh in order to draw the shock-delivering device in the opposite direction. It will also be seen that from the arrangement of the gear shifting device shown in Fig. 1 that it will be impossible to have more than one gear in mesh at the same time.

In order to support the shock which is being formed by the operator of my device, yoke 30 and shocking arm 32 are provided. Shocking arm 32 is pivoted to a pedestal carried on the side of the machine at point 39. I provide a lever 36 having a spring catch 37 and a catch-actuating lever 88 attached thereto. It will be seen that by throwing lever 36 to the position shown in dotted lines that the shocking arm 32 may be removed after the shock has been formed and just before it is to be delivered to the ground.

In order to provide a device for righting the bundles of grain as they are delivered from the harvester, I provide a bundlerighting device such as 47. An inclined chute such as 45 receives the bundle of grain from the harvester and by gravity it will roll downward, the head of the bundle coming into contact with the curved abutting wall 46, allowing the butt end of the bundle to swing around and slide downward on to the shocking floor.

Numeral 40 designates a platform carried parallel with the ground and hinged to the rear end of platform l. Coil springs such as l1 are hung from side bars 42 and are attached to the outer edge of platf m 40, said springs being of suitlicient strength to support said platform until the weight of the shock has been placed thereon, which time platform 40 will tilt as is shown in dotted lines in Fig. 2 and allow the shock to settle upon the ground without being dropped the entire distance from platform f to the ground.

While operating my accessory, an attendant will stand in the approximate position shown in Fig. l and designated as 31. From this position he may pla e the bundles of grain on the shocking floor in their proper relation and when a shock has been assembled he will push. lever 36 forward, causing shocking arm 32 to swing outward. He will immediately draw lever 25 to the dotted position shown in Fig. 1 when gear 21 will actuate bar 27 backward and yoke 30 will push the shock along the sloping shocking platform to the ground behind the moving machine.

From the foregoing description it will be readily seen that the device of my invention provides an accessory to a harvester which will receive the bundles of grain delivered therefrom and which will provide a convenient shocking floor from which the completed shock may be delivered to the groimd with greatest facility. It will also be seen that l have provided a method for righting and delivering the bundles of grain butt end down to the shocking floor of my device which will be practically automatic in its operation and which will accomplish its work with the least difliculty.
